  [First Embodiment]

  FIG. 1 shows a configuration example of a wireless communication apparatus according to the first embodiment. The configuration shown in FIG. 1 is an example, and the present invention is not limited to such a configuration.

  A housing unit 2 illustrated in FIG. 1 is an example of a housing unit that configures the wireless communication device according to the present disclosure, and illustrates an example of a grounding structure of an exterior component formed of a conductor. For example, a substrate 8 having a functional component such as a wireless communication function unit formed therein is stored in the housing unit 2, and a mobile phone, a PC (Personal Computer), or the like is configured by a single unit or a plurality of units. For example, a first case portion 4 to which a functional component is fixed and a second case portion 6 constituting an exterior component of the wireless communication device are joined to the housing portion 2.

  In the first case portion 4, for example, a substrate 8 is held on the joint surface side with the second case portion 6. Further, on the exterior side of the first case portion 4, for example, an operation button of an unillustrated wireless communication device, an LCD (Liquid Crystal Display), or the like is installed. That is, the first case unit 4 is an example of a front case of a wireless communication apparatus that includes a user interface such as a display unit or an operation unit.

  The second case portion 6 is an example of a rear case on the exterior side of the wireless communication device. In the second case portion 6, for example, a decorative panel 10 is installed on a part or all of the exterior side. In the second case portion 6, a housing portion 11 for opening the panel 10 and a part of the terminal 12 that is electrically connected to the panel 10 is opened.

  The panel 10 is composed of a conductive member 13 such as a carbon fiber. Further, the panel 10 is covered with, for example, a resin member 15 on the upper surface side and the lower surface side of the conductive member 13. The film of the resin member 15 has, for example, an insulating function for preventing the carbon fiber from interfering with an electronic component such as an antenna disposed in the housing portion 2 and an outer shape protecting function for the carbon panel. The panel 10 shown in FIG. 1 has a laminated state in which resin members 15 are molded on the upper surface side and the lower surface side of the carbon fiber. Moreover, the carbon fiber which is an inside is exposed to the side surface edge part of the panel 10, for example.

  A terminal 12 is mounted inside the housing unit 2 for conducting the installed panel 10 and the substrate 8. This terminal 12 is made of, for example, a metal material. The terminal portion 12 includes a first terminal portion 14 that is in contact with the panel 10 and a second terminal portion 16 that is mounted on the surface of the substrate 8 and is in contact with a part of the first terminal portion 14.

  The 1st terminal part 14 is installed in the accommodating part 11 of the 2nd case part 6, for example. The first terminal portion 14 may be integrally formed with the second case portion 6, for example, with the resin of the second case portion 6, or may be fixed via an adhesive. Further, a part of the first terminal portion 14 may be fixed through the second case portion 6. Further, the first terminal portion 14 is fixed to a part or all of the surface on the lower surface side of the panel 10 facing the inner side of the housing portion 2 via the adhesive member 20. Further, the first terminal portion 14 is formed with, for example, a contact end portion 18 that is brought into contact with the side surface portion of the panel 10 at a part of the front end side. The contact end portion 18 is formed, for example, by bending a part of the first terminal portion 14 along the storage portion 11.

  The second terminal portion 16 is connected to, for example, a ground pattern formed on the substrate 8. For example, a part of the second terminal portion 16 is bent upward from the mounting surface of the substrate 8, and a spring structure is formed between the substrate 8 and the first terminal portion 14. Further, the second terminal portion 16 is bent with the contact portion with the first terminal portion 14 facing downward. As a result, the second terminal portion 16 generates a reaction force directed upward against the pressing of the first terminal portion 14 due to the installation of the panel 10, and comes into strong contact with the first terminal portion 14. And the conduction | electrical_connection state of the panel 10 and the board | substrate 8 is strengthened.

  In the housing part 2 shown in FIG. 2, for example, the first terminal part 14 is installed along two or four sides of the second case part 6 facing each other. The contact end 18 is arranged at the opening end of the storage portion 11 in accordance with the side end of the panel 10. Thus, the installation position of the panel 10 is determined in the storage unit 11 according to the arrangement of the contact end portions 18.

  In addition, the 1st terminal part 14 may be formed in single according to the magnitude | size of the opening part of the accommodating part 11, for example.

  The second terminal portion 16 is arranged in parallel with the first terminal portion 14, for example. For example, the number of the second terminal portions 16 may be determined according to the number of contact end portions 18 or the size of the substrate 8 or the panel 10.

  FIG. 3 shows an example of the assembly process of the casing. The processing contents and processing procedures shown in FIG. 3 are examples, and the present invention is not limited to such a configuration.

  This assembling process shows an example of an assembling method or manufacturing method of the wireless communication device of the present disclosure. In this assembly procedure, for example, the second terminal portion 16 is installed on the substrate 8 (S1). The installation position of the second terminal portion 16 is determined in consideration of, for example, the arrangement position of the first terminal portion 14, the size of the storage portion 11, or interference avoidance with other components mounted on the substrate 8. The

  The substrate 8 provided with the second terminal portion 16 is disposed at a position set in the first case portion 4 (S2). The substrate 8 is fixed to the first case portion 4 with fastening parts such as screws, for example.

  If the board | substrate 8 is installed, the 2nd case part 6 will be installed facing the 1st case part 4 (S3). The first case portion 4 and the second case portion 6 are fixed using, for example, fastening parts.

  The 1st terminal part 14 is installed with respect to the accommodating part 11 opened by the 2nd case part 6 (S4). At this time, the 1st terminal part 14 is mounted according to the position of the 2nd terminal part 16 mounted in the board | substrate 8, for example, and arrange | positioned toward the accommodating part 11 side.

  And the panel 10 is installed through the adhesive member 20 with respect to the 1st terminal part 14 (S5). The panel 10 is arrange | positioned in the position where a side surface end part contacts with the contact end part 18 of the 1st terminal part 14 arrange | positioned at the accommodating part 11, for example.

  According to such a configuration, in the assembling process of the wireless communication device, it is not necessary to remove the resin member coated on the panel, and the assembling process can be simplified. Moreover, the side surface part of a panel and a terminal can be made to contact reliably because the arrangement position of a panel is determined by the terminal part installed in the housing | casing. By forming either one of the terminal portions into a spring shape, the contact state between the terminals can be further strengthened. Further, the resin material is not required to be deleted by arranging the terminal portion in accordance with the exposed portion of the carbon fiber. As a result, this panel can be reused for other wireless communication apparatuses having different ground terminal arrangement positions.

  The first terminal 42 shown in FIG. 5 has a distal end bent toward the panel 10 disposed in the storage portion 37, for example. By this bending, the terminal 42 presses the side surface portion of the panel 10 disposed in the storage portion 37. The first terminals 42 are disposed so as to face each other in the left-right or front-rear direction, for example, over the entire circumference of the panel 10 disposed in the storage portion 37. For example, the panel 10 is pressed from the opposing direction by the first terminal 42, so that the panel 10 can be firmly in contact with the first terminal 42 and is held in the storage portion 37.

  6, 7, and 8 show configuration examples of the wireless communication apparatus.

The wireless communication device 30 in the closed state is in a stacked state with the front side of the casing unit 32 on which the display panel 48 or the like is installed facing the front side of the casing unit 50, for example.

  The panel 10 is installed on the back side of the casing 32 as an exterior member of the wireless communication device 30. The panel 10 is disposed in the storage portion 37 via the adhesive member 20. The adhesive member 20 is a means for fixing the rear case 36 and the panel 10 and is composed of, for example, a double-sided tape. The adhesive member 20 may use a tape or putty having a predetermined thickness. The panel 10 may be joined to the storage portion 37 through, for example, a packing having a predetermined thickness.

On the substrate 8, for example, the second terminals 44 are surface-mounted on the front side or the back side. Further, the LCD module 56 is connected to the substrate 8 through the front case 34 by a flexible cable (not shown), for example.

  On the substrate 8 shown in FIG. 9, for example, the second terminals 44 are mounted along the periphery. The mounting position of the second terminal 44 may be set according to the arrangement position of the first terminal 42 as described above. The magnitude | size of the accommodating part 37 (FIG. 7) in which the 1st terminal 42 is arrange | positioned is set with the panel 10 installed. Therefore, the mounting position (second terminal 44a) of the second terminal 44 mounted on the substrate 8 may be arbitrarily set according to the size of the panel 10, for example.

  The mounting orientation of the second terminal 44 is set for each side of the substrate 8, for example. On the short side of the substrate 8 shown in FIG. 9, the tip end portion of the terminal 44 is bent in the center direction of the substrate 8. Further, on the long side of the substrate 8, for example, the tip end portion of the terminal 44 is arranged to bend in any short side direction of the substrate 8. This mounting direction may be determined by, for example, the length of the side of the substrate 8 or the number of second terminals 44 mounted on one side.

  FIG. 10 shows an arrangement example of antennas mounted on a substrate.

  The wireless communication device 30 is provided with one or more antennas that perform a call function, a data communication function, and the like.

  Next, a configuration example of components installed in the wireless communication device 30 is shown. FIG. 12 shows a configuration example of the carbon panel.

  The panel 10 shown in FIG. 12A is formed in a flat plate shape, and a pattern formed by, for example, a carbon fiber or a specific color is applied to the surface. As shown in FIG. 12B, for example, a plurality of carbon fiber members 80 and 82 are laminated on the panel 10, and resin members 84 are laminated on the upper surface side and the lower surface side thereof. That is, the carbon fiber members 80 and 82 are covered with the resin member 84 on the upper and lower planes. Further, the side end portions of the carbon fiber members 80 and 82 are not covered with the resin member 84.

  The carbon fiber members 80 and 82 have different patterns on the upper surface side and the lower surface side, for example. In the wireless communication device 30, for example, carbon fiber members 80 and 82 having different patterns may be combined. Further, the carbon fiber members 80 and 82 may be formed with a pattern by changing the transmittance or reflectance of external light by changing the thickness, for example.

  In addition, in the wireless communication device 30, for example, the carbon fiber member 80 arranged on the upper layer side is used for decoration, and the carbon fiber member 82 arranged on the lower layer side is used as a shield member for electronic components mounted therein. May be.

  13 to 16 show configuration examples of the rear case and the terminals.

  In the storage portion 37 formed on the front surface side of the rear case 36 shown in FIG. 13, a mounting surface 90 for mounting the panel 10 is formed on the bottom surface side. The panel 10 is installed on the mounting surface 90 via the adhesive member 20. On the mounting surface 90, for example, a window portion 92 for exposing the substrate 8 installed on the back side is formed. The window portion 92 exposes a part of the functional components mounted on the substrate 8 toward the exterior side of the wireless communication device 30. The window portion 92 is used, for example, for heat dissipation of mounted components of the substrate 8, weight reduction of the wireless communication device 30, or maintenance for the substrate 8.

  In addition, a plurality of tip portions of the first terminals 42 are exposed on the peripheral edge of the side surface of the storage portion 37. As shown in FIG. 14, the first terminal 42 is installed at a height at which the contact end portion 100 contacts the carbon fiber members 80 and 82 with respect to the panel 10 placed on the placement surface 90.

  The first terminal 42 shown in FIG. 15A includes a contact end portion 100 that is brought into contact with the panel 10, a body portion 102, and a connection portion 104 that is electrically connected to the second terminal 44. The contact end portion 100 constitutes the contact end portion 18 described above, and is brought into contact with the side surface end portion of the panel 10 so as to be electrically connected to the carbon panel members 80 and 82.

  The contact end portion 100 is exposed from, for example, the storage portion 37 of the rear case 36 (FIG. 14). As shown in FIG. 16A, the contact end portion 100 is formed in, for example, a substantially triangular shape, and is formed so that the apex of one bent portion is brought into contact with the panel 10 installed. Further, the contact end portion 100 has a spring function of pressing against the touched panel 10 due to the protruding shape toward the storage portion 37 side. What is necessary is just to set the protrusion amount L2 of the contact end part 100 by the magnitude | size of the panel 10 with respect to the accommodating part 37, the width | variety of the mounting surface 90, etc., for example.

  The body portion 102 is accommodated in the rear case portion 36 and held at a predetermined arrangement position. Thereby, the arrangement position of the contact end part 100 and the connection part 104 is fixed to the first terminal 42, and the contact position with the panel 10 and the second terminal 44 can be prevented from shifting. The contact end portion 100 and the conductor portion 102 are formed of a series of members, for example, and as shown in FIG. 16B, the width W1 of the contact end portion 100 and the width W2 of the conductor portion 102 are formed equally. .

  The width W1 of the contact end portion 100 may be set larger than the width W2 of the conductor portion 102, for example, in order to give a contact strength with the panel 10.

  The connection part 104 shown to FIG. 15B is formed in the height h1 downward from the trunk | drum 102, for example. The connecting portion 104 is an example of one end of the terminal 42 and is bent so as to be horizontal, for example, in the same direction as the protruding direction of the contact end portion 100. The height h1 is set to be equal to the distance at which the connecting portion 104 protrudes to the rear side of the rear case 36. The protruding length L3 of the connecting portion 104 shown in FIGS. 16A and 16B may be determined based on, for example, the shape of the interior of the rear case 36 and the position of the second terminal 44 mounted on the substrate 8.

  On the back side of the rear case 36 shown in FIG. Inside the space portion 110, for example, the body portion 102 and the connection portion 104 of the first terminal 42 formed integrally with the rear case 36 are disposed. A through hole that exposes the first terminal 42 is formed on the side surface of the storage portion 37. The body portion 102 is disposed in the rear case 36 through the through hole.

  The connection part 104 is arrange | positioned in contact with the back side of the accommodating part 37, for example. As shown in FIG. 17B, for example, only a part of the tip of the connecting portion 104 is set to a length at which the connecting portion 104 is arranged on the back side of the mounting surface 90. In the housing 32, the first terminal 42 and the second terminal 44 are brought into contact with each other in the space 110 of the rear case 36 and are conducted. Thus, the rear case 36 is configured such that the terminals 42 and 44 are not exposed from the window 92 when the panel 10 is removed.

  According to such a configuration, any of the following effects can be obtained.

  (1) With respect to a panel in which resin members are laminated on the upper and lower surfaces of a carbon fiber member, the processing is not performed such as removing the resin member of the panel by bringing a terminal into contact with the side surface and making it conductive. Can be grounded.

  (2) The rear case and the terminal are integrated, and the terminal is arranged on the peripheral side with respect to the panel arrangement position, so that the rear case and the panel can be arranged at the same height, for example, and the wireless communication device is thinned. Can be achieved.

  (3) Since the arrangement position of the panel is determined by the terminal installed in the casing, the side surface of the panel and the terminal can be reliably brought into contact with each other.
